Definitions

  • the invention relates to a method for routing telecommunication connections (TC connections) to a mobile radio terminal. It also relates to a mobile radio gateway and a mobile radio terminal that are suitable for participating in the implementation of the method.
  • So-called mobile radio gateways are also known which provide an interface between one or more telecommunications mobile radio networks and any other networks, for example a telecommunications fixed network or an IP network provide.
  • a mobile radio gateway is called by the user of another network and forwards the desired connection via a mobile radio channel into the mobile radio network in which the called subscriber is located.
  • the mobile radio gateway implements the functionality of a mobile radio telephone and, as it were, calls the called subscriber as a mobile radio telephone.
  • Mobile radio gateways therefore have the same mobile radio modules as are used in mobile radio terminals (cell phones). Such cellular gateways are for example from the DE 103 14 144 A1 known.
  • a mobile radio gateway contains a large number of SIM cards for the managed mobile radio channels. Any SIM cards from different network operators can be used.
  • IMSI International Mobile Subscriber Identity
  • a SIM card has a PIN number (PIN - Personal Identity Number), security-relevant data such as communication keys and security algorithms, user-specific data such as abbreviated dialing numbers and network-specific data such as the identification of the current area.
  • PIN number PIN - Personal Identity Number
  • security-relevant data such as communication keys and security algorithms
  • user-specific data such as abbreviated dialing numbers
  • network-specific data such as the identification of the current area.
  • a SIM card personalizes a mobile radio terminal with regard to the user and with regard to the network operator and enables the network operator to bill call charges.
  • SIM servers are also known.
  • SIM cards for mobile radio communication are provided at a central location or a central computer.
  • a SIM card is requested by a cellular gateway from the central computer and made available by the latter to the cellular gateway.
  • This provision of the SIM card for cellular communication does not take place physically.
  • Only the information that identifies a SIM card and reflects its functionality is transmitted to the cellular gateway via remote data transmission.
  • the SIM card is thus virtually virtually on a central computer and its functionality is, if necessary, emulated on the mobile radio gateway on the basis of specific information and data transmitted from the central computer. This enables the use of a central SIM card pool for one or more cellular network gateways.
  • Such SIM servers are for example in the DE 103 11 980 A1 described.
  • the US 2007/076760 A1 describes a method and a network for acquiring device information from mobile terminals. It is provided that after a SIM card is changed, this is recognized in the mobile device and data that identify the new SIM card are transmitted to a SIM switch detector (SSD) in a central system for the purpose of storing the new SIM information in a database.
  • SIM switch detector SSD
  • the present invention is based on the object of providing a method for routing telecommunication connections (TC connections) to a mobile radio terminal which reduces the costs associated with conventional roaming and nevertheless ensures the connectivity of the mobile radio terminal.
  • the present invention is also based on the object of providing a mobile radio gateway and mobile radio terminal which can be used in such a method.
  • this object is achieved by a method with the features of claim 1, a mobile radio gateway with the features of claim 12 and a mobile radio terminal with the features of claim 15. Refinements of the invention are given in the subclaims.
  • the method according to the invention is based on the situation that a mobile radio terminal is in the reception range of a current mobile radio network that is not the same as a home network of the mobile radio terminal.
  • the mobile radio terminal is located in a foreign country in relation to the country in which its home network is located.
  • the current cellular network can, however, also be any other cellular network of the same state.
  • the mobile radio terminal has a first SIM card which is assigned to the home network and to which a first telephone number is assigned.
  • the first SIM card of the mobile radio terminal is replaced by a second SIM card assigned to the current mobile radio network, to which a second telephone number is assigned.
  • the replacement is usually a physical replacement of the first SIM card by the second SIM card by the user of the mobile radio terminal. If the mobile radio terminal is designed in such a way that it can contain several SIM cards at the same time, the replacement of the first SIM card by the second SIM card can also involve deactivating the first SIM card and the second SIM card is activated.
  • a message is automatically generated in the mobile radio terminal, which has at least the following information: On the one hand, the second call number assigned to the second SIM card, and on the other hand, at least one piece of information that identifies the replaced SIM card.
  • This information can be, for example, the first call number assigned to the replaced SIM card and / or at least one piece of identification information relating to the replaced SIM card.
  • the at least one item of information that identifies the replaced SIM card can, however, also be other information, for example private information agreed code or a specific identification number that was assigned to the first, replaced SIM card.
  • This automatic generation of a message takes place, for example, by a software application that is implemented on the mobile radio terminal.
  • the message is generated automatically in the sense that the software application independently compiles the information contained in the message and embeds it in a message. It can, however, be provided that the application asks the user of the mobile radio terminal whether he wants a corresponding message to be generated automatically, and the user has to confirm this.
  • the generated message is automatically sent from the mobile radio terminal to a mobile radio gateway, the mobile radio gateway being connected to the home network, that is to say to the network of the first SIM card, directly or via another network.
  • the message is sent to the cellular gateway automatically.
  • the message is sent to the mobile radio gateway as an SMS message.
  • the new phone number assigned to the second SIM card is automatically provided via the sender information of the SMS message.
  • the method according to the invention also provides that every TC connection directed to the first call number is now routed to the mobile radio gateway. This can be achieved, for example, in that a partner SIM card of the first SIM card is registered by the mobile radio gateway in the home network of the first SIM card after the message has been received.
  • a partner SIM card of the first SIM card is registered by the mobile radio gateway in the home network of the first SIM card after the message has been received.
  • TC connections directed to the first telephone number of the first SIM card that is, to the standard telephone number of the mobile radio subscriber
  • the mobile radio gateway then assigns such a TC connection to the second SIM card and / or the second call number assigned to the second SIM card on the basis of the information contained in the message. On the basis of the message received, the mobile radio gateway is informed of the current, temporary call number the mobile radio gateway has in the current mobile network and can assign the TC connection directed to the first call number to this current second call number or the second SIM card .
  • such a TC connection is now forwarded from the mobile radio gateway via at least one communication network to the mobile radio terminal provided with the second SIM card using the second call number contained in the message.
  • the communication network via which the telecommunications connection is forwarded by the mobile radio gateway generally does not include a mobile radio network (apart from the current target cellular network into which the mobile radio terminal with its second SIM card is registered). Rather, an inexpensive network is used, via which the connection is forwarded to the current cellular network in which the second SIM card is registered.
  • a first exemplary embodiment of such a communication network is the international fixed network (TDM network), via which telecommunication information can be transmitted much more economically than via roaming between mobile radio networks.
  • TDM network international fixed network
  • the communication network via which a TC connection is routed from the mobile radio gateway to the current mobile radio network is an IP network such as the Internet.
  • the method according to the invention thus avoids conventional roaming with the aid of standard mobile radio functions, local SIM cards and the use of a mobile radio gateway and thereby realizes a considerable potential for cost savings.
  • a mobile radio user who uses a cheaper local SIM card, for example when traveling abroad, can still communicate comfortably and inexpensively with users of the domestic mobile radio network using the method according to the invention.
  • No other devices are used in the current cellular network apart from the user's normal mobile radio terminal and the user is independent of all Internet connections. All incoming and outgoing calls work as usual, but the costs associated with traditional roaming are avoided.
  • the mobile radio user does not need WLAN hotspots, mobile Internet connections or a corresponding VoIP solution to implement the method according to the invention, which can also incur considerable costs in some cases. Nevertheless, you can still be reached under the known mobile phone number.
  • SIM card in the context of the present invention denotes any plug-in card that uniquely identifies a network subscriber, so that a mobile radio device with such a plug-in card can be assigned to a specific network operator and can receive a specific call number.
  • SIM card thus not only denotes plug-in cards for identifying a network subscriber in the GSM standard, but also plug-in cards for identifying a network subscriber of any other current or future mobile radio standards.
  • the mobile radio terminal is initially located in a foreign country in relation to the country in which its home network is located.
  • the current cellular network is a foreign cellular network and the first SIM card is replaced by a second SIM card assigned to the foreign cellular network.

  • the message is first received by the mobile radio gateway and this then informs the SIM server of the receipt of the message, whereupon the data relevant for an authentication in the home network are sent from the SIM server to the mobile radio gateway.
  • the message generated automatically in the mobile radio terminal is sent via the SIM server to the mobile radio gateway and is thus first available to the SIM server, whereupon the SIM server sends the data relevant for authentication in the home network to the Cellular gateway sent.
  • Partner SIM cards are known per se. It is a SIM card that is assigned the same phone number as the actual SIM card, but which has a different IMSI. The partner SIM card must be applied for and available before the procedure is carried out.
  • a TC connection directed to the first call number is routed to the mobile radio gateway in that the mobile radio terminal sets constant call forwarding to the mobile radio gateway before the SIM card is exchanged.
